171 When Abram was ninety-nine years old, the Lord appeared to Abram and said to him, "I am Almighty God; walk before Me and be blameless. 2 And I will make My covenant between Me and you, and will multiply you exceedingly." 3 Then Abram fell on his face, and God talked with him, saying:
4 "As for Me, behold, My covenant is with you, and you shall be a father of many nations. 5 No longer shall your name be called Abram, but your name shall be Abraham; for I have made you a father of many nations. 6 I will make you exceedingly fruitful; and I will make nations of you, and kings shall come from you.
7 And I will establish My covenant between Me and you and your descendants after you in their generations, for an everlasting covenant, to be God to you and your descendants after you. 8 Also I give to you and your descendants after you the land in which you are a stranger, all the land of Canaan, as an everlasting possession; and I will be their God." 9 And God said to Abraham: "As for you, you shall keep My covenant, you and your descendants after you throughout their generations. 10 This is My covenant which you shall keep, between Me and you and your descendants after you: Every male child among you shall be circumcised; 11 and you shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between Me and you. 12 He who is eight days old among you shall be circumcised, every male child in your generations, he who is born in your house or bought with money from any foreigner who is not your descendant. 13 He who is born in your house and he who is bought with your money must be circumcised, and My covenant shall be in your flesh for an everlasting covenant. 14 And the uncircumcised male child, who is not circumcised in the flesh of his foreskin, that person shall be cut off from his people; he has broken My covenant."

(Read Genesis 17:1-6)
The covenant was to be accomplished in due time. The promised Seed was Christ, and Christians in him. And all who are of faith are blessed with faithful Abram, being partakers of the same covenant blessings. In token of this covenant his name was changed from Abram, "a high father," to Abraham, "the father of a multitude." All that the Christian world enjoys, it is indebted for to Abraham and his Seed.
Commentary on Genesis 17:7-14
(Read Genesis 17:7-14)
The covenant of grace is from everlasting in the counsels of it, and to everlasting in the consequences of it. The token of the covenant was circumcision. It is here said to be the covenant which Abraham and his seed must keep. Those who will have the Lord to be to them a God, must resolve to be to him a people. Not only Abraham and Isaac, and his posterity by Isaac, were to be circumcised, but also Ishmael and the bond-servants. It sealed not only the covenant of the land of Canaan to Isaac's posterity, but of heaven, through Christ, to the whole church of God. The outward sign is for the visible church; the inward seal of the Spirit is peculiar to those whom God knows to be believers, and he alone can know them. The religious observance of this institution was required, under a very severe penalty. It is dangerous to make light of Divine institutions, and to live in the neglect of them. The covenant in question was one that involved great blessings for the world in all future ages. Even the blessedness of Abraham himself, and all the rewards conferred upon him, were for Christ's sake. Abraham was justified, as we have seen, not by his own righteousness, but by faith in the promised Messiah.
